It’s a remarkable achievement for a sector that just keeps breaking records, as growth heads in one direction and costs in the other. And it’s worth noting that just 10 years ago there were only about 20,000 systems installed across the entire country.

Month after month we have seen record-breaking growth that, as the chief of the Australian Energy Market Operator likes to put it, averages out to six rooftop solar panels installed every minute somewhere around the country. If you count panels from large-scale solar, it’s more like 12-20 per minute.

Like the data from the Clean Energy Regulator last week – which highlighted the top solar postcode for each state and territory – the CEC data, put together with the help of SunWiz solar analyst Warwick Johnston, shows a rooftop solar market that is still well and truly booming, led by Queensland.

According to the CEC, the Sunshine State currently boasts four of the nation’s top five solar postcodes, starting with Bundaberg in the state’s centre.

Mandurah in Western Australia holds second spot on the rooftop ladder, followed by three more Queensland locations: Hervey Bay, Caloundra and Toowoomba.

(Ed Note: These findings differ from those of the CER last week because the CER is counting uptake of all small-scale solar technologies, including solar hot water.)

And you can see the top three household solar postcodes for each state in the table below:

But what is really interesting to note from the CEC report, particularly as a federal election looms, is the political status of those and other top solar postcodes.

As you can see in the list below, *almost all one of the CEC’s top five solar postcodes in Queensland and WA reside in Liberal or Liberal-National Party held electorates – both at the state and federal levels.

But they may not be for long, particularly if the federal government continues to play dumb on renewables and instead align itself with the nebulous concepts of “24/7” and fair-dinkum power.

As recent election and by-election results around the country have shown – and particularly strikingly in Victoria last month – voters are not only embracing renewable energy technologies like rooftop solar, they are making the connection between them and cheaper electricity.

“We’ve had a decade of polls which show strong support for renewable energy like solar and wind, yet somehow it has been beyond our federal politicians to deliver meaningful climate and energy policy during this time,” said CEC chief Kane Thornton in comments to One Step.

“So instead of looking to politicians for leadership, the people living in two million Australian homes across the country have shown they are prepared to invest their own money in solar power. This is a huge constituency, and politicians ignore this new reality at their own risk.

“All parties should be listening to their communities on this issue, because there are ultimately 3-5 million people of voting age who are unlikely to buy into a cost-of-living scare campaign about renewable energy when their lived experience is the opposite – solar power helps save money for you and your family by reducing your power bill.

“And based on the number of systems being installed, several thousand new people will have that same experience every week.”

A cursory look at the list of above candidates shows little outward sign of support for renewable energy, but it remains to be seen how they might campaign on the issue in an election.

Keith Pitt, the Member for Hinkler, which includes Bundaberg, has confirmed he will be** contesting the next federal election, but resigned from the Cabinet in August at around the time of Malcolm Turnbull’s ousting by Scott Morrison.

In a statement at the time, he said he would “always put the national interest and the interests of my constituents above my own. I will always put reducing power prices, before Paris.”

Andrew Hastie who oversees Mandurah is noted as one of the rebel Liberal Party backbenchers, alongside Tony Abbott, who brought Turnbull’s National Energy Guarantee policy undone, and then Turnbull himself.

John McVeigh, the federal member for Groom, looks to be more on the fence on renewables, although it is worth noting he was previously a state minister under former Premier Campbell Newman, who led a stridently anti-renewables government, with a particular dislike of rooftop solar.

*This article has been corrected to show that the WA suburb of Mandurah is in a Labor held state electorate, and a Liberal Party held federal seat. It was also corrected to show that the federal member for Hervey Bay is LNP MP Keith Pitt, who will be contesting the next federal election (**a previous version of the article suggested he would not).

5 responses to “Two million Australian households now have rooftop solar – and they vote”

I would like to think that everyone who lives under a solar roof would put the COALition-Hanson Government last on their ballot.

But I am genuinely surprised that some solar owners don’t see the potential and value for renewables for the grid. And many with no concern for emissions but admit installing solar to reduce their own bills. Very confusing.

Hi Rod. If the only issue exercising the minds of punters was solar / RE before they scribble away on ballot papers with their 1,2.3….then yes, ‘solar households’ would be putting the RE recalcitrants political parties last. But elections are not single issue affairs and there are plenty of people who are also rusted on voters whose loyalty is unwavering no matter how good or how bad their political party is no matter what the issue / policy involved. I used to be a rusted on Labor voter but now I split my vote for Labor ( HoR ) and for Greens ( Senate ) – Newstart, Asylum Seekers and that dreadful action under Julia / Labor to shunt single Mums onto the lower Newstart were cumulative beakers for me.

It’s quite correct that the figure of around 3-4 million, maybe more, may be living in households with solar power, and growing. Are LNP politicians blind, deaf, or just dumb. There will be a major wipe-out at the next federal election, and those with their head in the sand will suffocate into nothingness.
